Oxygen

氧(Oxygen),元素符号O,位于元素周期表第二周期ⅥA族。1774年英国科学家约瑟夫·普里斯特利(J.JosephPriestley)用透镜把太阳光聚焦在氧化汞上,发现一种能强烈帮助燃烧的气体。安托万-洛朗·拉瓦锡(Antoine-LaurentdeLavoisier)研究了此种气体,并正确解释了这种气体在燃烧中的作用。氧是地壳中最丰富、分布最广的元素,也是构成生物界与非生物界最重要的元素,在地壳的含量为48.6%。单质氧在大气中占20.9%。[1]

  • DOxygen的词根来源于Document(文档)和Oxygen(氧气)

    DOxygen的词根来源于Document(文档)和Oxygen(氧气),它是一个功能强大、使用方便且支持各种操作系统和编程语言的代码文档生成系统。DOxygen由荷兰人Dimitri van Heesch.开发,并且在GNU公共许可证(GPL)下发布,目前已经成为各主要的Linux发行版的附带组件。众多重量级的软件项目(如KDE,Qt、ACE库等)都选用DOxygen作为其编档工具生成项目文档。 DOxygen最初在Linux下开发,但已经被移植到多个操作系统平台下,包括Unix的各发行版本、MS Windows和Mac OS。DOxygen目前最新的版本是1.3.6,支持的编程语言包括 C++,C,Java,IDL(CORBA和MS风格),对Objective-C, PHP, C#和D语言也有部分支持。

  • A Single-Chip Pulsoximeter Des

    This application report discusses the design of non-invasive optical plethysmographyalso called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). Thepulsoximeter consists of a peripheral probe combined with the MCU displaying theOxygen saturation and pulse rate on a LCD glass. The same sensor is used for bothheart-rate detection and pulsoximetering in this application. The probe is placed on aperipheral point of the body such as a finger tip, ear lobe or the nose. The probeincludes two light emitting diodes (LEDs), one in the visible red spectrum (660nm) andthe other in the infrared spectrum (940nm). The percentage of Oxygen in the body isworked by measuring the intensity from each frequency of light after it transmitsthrough the body and then calculating the ratio between these two intensities.

  • Thin Film Metal-Oxides

     This chapter surveys the high temperature and Oxygen partial pressure behavior of complex oxide heterostructures as determined by in situ synchrotron X-ray methods. We consider both growth and post-growth behavior, emphasizing the observation of structural and interfacial defects relevant to the size-dependent properties seen in these systems.

  • 血氧仪核心硬件电路设计及Multisim仿真

    为了实时检测血氧量,能使缺氧特别敏感的脑组织或心脏类疾病患者得到及时治疗,采用近红外双波长透射式光电脉搏血氧测定法,以H桥电路对发射光源进行控制及通用运算放大器搭建滤波电路。运用参数理论计算和计算机仿真结果相对比的方法,通过Mu ltisim软件对所设计电路进行仿真,仿真结果与理论参数计算相吻合,证明了电路参数设计的可行性,为血氧仪的实物制作提供参考。For real-time detection of Oxygen saturation for timely treatment of the brain or heart,which are very sensitive to Oxygen inadequacy,the near-infrared wavelengths double photoelectric pulse oximeter transmission method is adopted.The illuminant is controlled with the H bridge circuit and the filter circuit is built with general op-amps.Parameters by theoretical calculation is compared with the computer simulation results in Multisim and satisfactory results are obtained.It is shown that the design of the circuit parameters is feasible and can be a help in making the physical blood-Oxygen monitor.
